You've got a point. Don't forget "brandy-brown eyes" and horrible cancer metaphors! I also couldn't stand his original heroic characters. I know most people love Tenel Ka, but I couldn't stand her, and her reasoning for not replacing the arm she lost... Yeah, I know, people say that means she's badass, but I just saw it as incredibly stupid. And a big hollowed-out rancor tooth would make a horrible lightsaber handle!
I'm painfully lightside, my characters always disagreed with him, and I don't like how his stories always turn into "And then we killed everything" - I love Dark Side trappings and amnesiac dissonance, yeah, but I always prefer characters who try to avoid death and maiming - but I love his voice, hearing him tell those stories, and how if you get far enough in his sidequest he voices his doubts about the rightness of the Mandalorian way, and how fighting isn't really enough anymore. Or something. Haven't played the game in a few years. I was sad that he was just Mandalore in the sequel. I could listen to his VA tell stories all day.
But I really have no idea why he stayed with the group past Taris. Was he really that bored? Did he claim half-ownership on the Ebon Hawk?
